What is a vibrating fluidized bed dryer
With the development of multi-stage drying, vibrating fluidized bed (VFB) has been applied. Its basic structure is similar to that of an ordinary fluid bed dryer.
The working principle of vibrating fluidized bed dryer
The material is fluidized by the dual action of mechanical vibration and perforated airflow, and moves forward in the form of a piston under the action of vibration, and supplies heat to the material layer by convection, conduction and radiation, which can achieve drying purpose.
Advantages of vibrating fluidized bed dryer
- Vibrating fluidized bed dryers can significantly reduce energy consumption because the conveying of materials is accomplished by vibration, and the supplied hot air is only used for heat and mass transfer.
- In addition, due to the strong vibration of the bed, the resistance to heat and mass transfer is reduced, which increases the drying rate of the vibrating fluidized bed drying equipment.
- At the same time, the agglomerated or highly dispersed materials that are not easy to fluidize or are easily entrained during fluidization can also be dried smoothly.
- Overcome the common fluidized bed easy to produce back mixing, channel flow, sticking to the wall and other phenomena.
